Hello Over the past couple of years I have put together the etched components and 3D printed parts to build a S Scale model of the above locomotive. Recently I have shared the parts with another member and so decided to put the build details here. Many members of the society scratch build and very few would be interested in this prototype, but I will share what I have and if anyone else is interested then please make contact. All parts will be available at cost, this is my hobby not a business. I am not an expert kit builder or modeller and some of my methods may not be the best. Happy to take suggestions for improvement. The underlying principle is to keep the model simple - whilst the model is dimensionally reasonably accurate it is not a fine detail model....but it can be made to run nicely with simple hand tools and a soldering iron. I will document the build over a number of weeks.....but here is a starter. Prototype info The B&M ordered six of these locos and the design was based on a copy of the GWR metro tank. B&M aquired six locos, between 1888 and 1904. Five of the engines survived into GWR ownership and were assigned numbers 1402/12/60/52/58 but only one (No 11) actually carried a GW number 1460. It is unlikely that 1460 actually performed operational duties in the GWR but it does open the door for anyone modelling the GWR to use this model.

i have now rebuilt my models of the sharp small passenger loco (albion) as used by the B&M (USK and WYE). I took some artistic licence and put a cab on the model USK. Does anyone know where i can get a drawing of "De Winton from"? Many thanks for any help you can offer.

I now have 10, 11 and 12 spoke tender wheel centres for our 3'7" society tyre should anyone be interested.

that is a work of art

Its a copy of the prototype made from a very good GA of the original loco. The etches and 3d prints are something i have drawn and improved on over the past couple of years.....email me direct and we can sort something out.

Ian - I have some etches for the attached.....it is a Brecon and Merthyr Stephenson 240. Happy to help get you started but maybe not what you had in mind. Longish way from LNWR. My standards are not the best but it can be made to run.....

thank you - i did not realise that we had something in the store let me take a look.

I have a question please...... What is the best way to configure the W Iron support / Axle support/compensation for a short six wheel coach? Many thanks in advance.

Thank you Phil - very helpbful......so the commercially made gauge 2 that Bing and others made.....was this compromised in some way between track gauge and the exact scale.....bit like OO and 4mm.... Do you know of anyone whop may have gauge 2 standards....there just seems to be a lack of any real info on this gauge.

Just finished my model of B&M WYE Locomotive. It is the very early version pre brakes. The tender is for a later model of the same loco.....just need to make a earlier version but it is fine to support a test run. 3D printed Drivers, Plunger Pickups as per an earlier post - all etched or 3D printed with compensated beams on the Drivers. Buffers Markit....the brass boiler safety valve cover and boiler band is 3D brass printed by Shapeways.

it is 3 rail.......i would make my own track........could i use gauge 1 rail do you think?

I am an S Scale modeller but want to build a Gauge 2 garden railway so that I can run this beautiful loco I aquired a few years back. If anyone models in Gauge 2 I would be keen to hear their experiences....

Thank you Jim, I cannot take the credit on the leading wheel. This is a 12 spoke Markit wheel (prototype is an 11 spoke), I need to make one. My coach stock should be 10 spoke but I found the Alan Gibson wheels touched the chairs. Whereas suprisingly the standard Markit tyre depth is less. I am going to 3D print some coach wheels, similar to your wagon wheels, just not got round to it yet....so I asked Markit nicely and he set his 17mm 12 spoke wheel on a 30.7mm axle. I have plenty of spares if anyone is interested. I was going to send a couple to our Parts officer so he is also aware, Plus Markit made a load of S Scale 2mm pin point axles that he has in stock. They came up 30.7mm rather than 30.5 as Alan Gibson are just fine. Apparently Alan Gibson pin points are 60 degree whereas Markits are 66 degree. the Markit pin point bearing is slightly slimmer so the difference is made up there.

I fitted a Hornby motor to a loco chassis today. First time I had tried a Hornby motor. I think it is a X7218, they are available on ebay for a tenner. Only been testing it a couple of hours but it is powerful and quiet.....the High Level Gearbox needed a few changes to fit but it did the job. No flywheel but the motor is big enought to be a flywheel in iteslf..... Anyone any experience with these motors?

Jim There is nothing wrong with the drawing.....it seems to have served the society well over the years..very clear and unambiguos. Thanks for the info.....i will take a look for a drawing too......the HMRS may have something.

help please on the society website there is a wheel profile.....is there a more detailed spec ....something similar to the one below that the Manchester Model railway society produce for EM?

Here are the brass wheels.....first time I have used brass.....On the CAD i profiled the spokes but this has got a little lost in the printing process..... Challenge I have is that you have to allow for shrinkage as the metal cools....with steel i worked it out at 0.25%. With brass it looks a little less.....but there will always be a little trial and error at the start.

Hello I appreciate that most S Scale modellers use split axles, therefore, the subject of pickups is not often discussed..... But I needed a solution for my plastic wheels. There are some good commercially available items but they have moving parts within the chassis and the wire to the pickup can become an obstacle to smooth operation. I found these pogo plunger pickups that are a good size and not too strong. Ebay has many of these types of contacts listed, they are typically soldered to printed circuit boards to support mechanical connection to external devices... The beauty of these devices is that the plunger moves within the body, any wire soldered to the body has no imparement on the movement of the plunger, therefore there are no moving parts within the loco frames. The challenge has been to find some that are of the right size and do not act as a brake.....the ones I have landed on have a 2mm diameter body, approx 8mm long and have a 12 gram compression. Plus they sit nicely inside a Markit 2mm insulated bearing and become a push fit into the frame. I have fitted them to a loco with decent sized wheels and a mashima motor and they run really well. Clearly any pickup has an element of friction but these work as well as anything else I have tried without constantly fiddling with wires .... Time will tell if these will wear well...

Hi Jim....good to hear from you. The wheels appear to be concentric....clearly there are limitations with any two components that screw together but I am running locos on my dodgy track and they are just fine....on my layout I am running my own wheels, Markit and Gibsons but will gradually align on my own wheels with society tyres across my rolling stock....which is only two wagons and seven coaches so not a particularly significant upgrade. I am talking to Paul....this wheel should really be a 5'6" but using a 5'7" tyre is OK. But I can expand this across any size of tyre.....I did look at Ultrascale but they do not have a front face on their tyres, something that makes aligning the tyre to the wheel that much harder. Not impossible but losing the inner face of the tyre loses a good reference point. I have developed a plunger pickup to go with the wheel using some readily available components.....I have some parts in the post ..... when they arrive I will share.....

Plastic Wheel #2 5'7" 18 Spoke 10" Throw PB. With or without balance Weights for Sharp Stewart Cambrian Albion or similar

Yes - great thread......i think our aproach is very similar. The power of 3D printing opens up a world of possibilities. S Scale is a great scale for 3D printing, It is big enough to compensate for minimum printing standards but also not so large that the irregularity of the printed surface cannot easily be smoothed out. I would encourage anyone who wants to use 3D printing as a means to create models to look seriously at S Scale. Whilst the geometry of wheels is relatively complex, Fusion 360 is an ideal CAD tool for the job.

Hello, I will photo and update as I produce different wheels. I have changed the orientation of the prints to a strip as it helps with printing. Balance weights can be added as required (or not). Balance weights are smooth no rivet detail. Plastic Wheel Number 1 - to fit 5'2" society tyre- 16 Spoke - 12" throw - PB.

Hello A member contacted me today and enquired about steel wheels so thought that I would provide an update. In the last society publication I shared some pricing for steel wheels. Unfortunately Shapeways will not print metal components on a spruce so i need to find an alternative. Individual wheels are too expensive when printed individually. However, what I can do is to join the wheels so that the rims just touch. The wheels will have to be seperated with a razor saw. This may seem odd but I tested on some plastic wheels and found that even with two flat edges the wheels help concentricity in the society tyre.... What I have not tested is the end to end design. Basically each wheel has a a printed axle. Within the axle and wheel there is a 1.5mm hole. This will take a 1.5mm glass fibre rod. There is then plastic collar that sits between the wheel and provides the insulation. But the proof is in the eating. I can modify the design and just print a 1/8 axle hole. The printed axle is smooth but not polished. Interested in others thoughts.

Throughout the past year I have been wrestling with building a Sharp Stewart Albion class. This locos appeared in many different forms across many companies. The challenge I have had is trying to find reliable prototype information. I have four drawings including a works GA but they all conflict. Even the works GA is different to early photos. That said I now have what I think is a boiler and accessories that is (in my opinion) the best interpretation of the drawings and photos. A defining feature of the boiler is the brass band that sits across the mid section of the boiler. I have made this a detachable feature so that it can be printed in brass or painted in metalic paint rather than trying to mask or paint this on after the loco has been painted. Sharing as a couple of members have expressed an interest. I have to smooth the boiler and then it should be ready for fitting to the footplate.

Hello In this section I will keep you updated on my 3D printed wheels. The plastic wheels are 3D printed to fit Markit S Scale Axles and Society Tyres. The price will be approximately £10 per set of four wheels This does not include axles or tyres that will have to be purchsased through the society stores. The metal wheels are still in development and may not be successful, I will update when I have some news. First up are some 5'2" 16 spoke 12" throw inline drivers, I will add pictures of other wheels as I make them or others ask me to make them for them. These wheels are an improvement on the ones I shared in the most recent society publication, the profile is slimmer but still supports the Markit nut.
